Patent GB-316392-A (GB)
Abstract: 316,392. Ward, T. E. June 25, 1928. Totalizators. - In a totalizator of the ballcounting type, the operator sets a horse-selecting pointer and thereby positions a type wheel and a bridge contact. He then operates a shaft so as to ink the type, advance a ticket, impress the number of the horse thereon, and complete the circuit to a ball-releasing mechanism. Normallv the latter releases balls to actuate the units drum of the horse counter but for coping with heavy work the balls may pass to an intermediate counting mechanism adapted to close circuit at each tenth actuation to release a ball for operating the tens drum. Ticket printing and issuing machine. A selecting handle 58, Figs. 3 and 4, is rigid with a type wheel 50 provided with a bridging contact bar 60 to connect one of a number of studs 69 with a contact ring 70, these being mounted on a non-rotary insulating disc 66 peripherally notched to be engaged by a pair of spring-controlled pawls 63 carried by the type wheel. This wheel and the disc 66 are mounted in a frame 57 vertically slidable in the casing 57<a> and under constant downward pressure by coiled springs 55<a>, 67a. Mounted above the frame is a shaft 74 provided with a handle 75 and when this is rotated a cam 73 on the shaft depresses the frame to impress the horse number on the ticket 83<a>. During the descent of the frame a wiper 77 on the cam rocks a lever 78 to pass an inking-roller 79 across the type and a pin swings a lever to' thrust the lowermost ticket of a pile into the protruding and printing position shown in Fig. 4. Ball-releasing mechanism. At each operation of a ticket-issuer a contact arm 71, Fig. 4, bridges a pair of spring contacts 72 to close circuit to an electromagnet 95, Figs. 1 and 8, adapted to rock a pair of blades 92, 93, rigidly connected at an angle to permit the escape of one ball at each operation. The balls are thus controlled in their passage. from one or more hoppers down the tubes 90 to the counting-apparatus. Counting-apparatus. The balls reaching the counting-apparatus may each represent wager units or tens of units. The unit balls descend a tube 90, Fig. 19, and as shown in Fig. 26 serve to connect a constantly driven toothed wheel 96 with a similarly toothed wheel 102 adapted to advance a units drum 115. The toothed wheels project through slots into the path of the descending balls and to prevent jamming, a flap 108 controlled by a spring 109 is provided. A spring-controlled pawl 110 is arranged to hold the wheel 102 except when a ball is passing. If a ball representing ten units is released this descends a tube 90<a> and through similar actuating mechanism operates the tens drum 121 through a ratchet and pawl 130 and a sleeve 116. Transfer-mechanism. The receiving wheel 107, Fig. 19, for each denomination is provided with a cam disc 113 (see also Fig. 22) adapted at transfer to raise a pawl 124 from holding a tenpin wheel 118 of the next higher denomination. At the same time a pin 113<a> on the disc actuates a pinion 123 that also engages the ten-pin wheel so that this with its numeral drum is consequently advanced one step. Installation. Fig. 1 shows an arrangement for four issuing-machiner the selecting circuits from which pass respectively to ball-releasing mechanisms for the four horses Z.Y.X.W. from which the balls pass to corresponding sections of a tenscounting apparatus V. As shown in Fig. 14 this comprises for each section driving and driven ball-connected wheels 151, 152 the latter of which is connected with a pin-wheel 154 having a recess 156 to allow, after each ten advances, the rocking of a spring-controlled lever 158 to close circuit for a magnet 163 in a section U so that a ball is released and descends a tube 90a to operate the tens drum of the horse counter. By opening the circuit and closing another including contact 165, a lever 164 may be operated by the pin wheel at each advance and so release unit balls in the section T. The balls from the units and tens counting-devices pass finally to wheels 185, 174 to control the operation of a grand total counter.
